fix: update health check URL in Jenkinsfile and reduce wait times in e2e tests

- Changed health check URL from localhost:8000 to localhost:3467 in Jenkinsfile.
- Reduced wait times in various e2e tests to improve performance and responsiveness.
- Cleaned up logging in middleware.py by removing unnecessary log statement.

These changes aim to enhance the CI pipeline efficiency and streamline the testing process.
